a basic tool kit... a good cordless drill to run stab jacks up and down (and socket to match, size slipped my brain just now), white fresh water hose (50 ft), rhino sewer hose (50 ft), clear elbow for sewer hose, flush wand and hose if you don't have an installed black tank flush, water pressure regulator, air compressor/battery charger/jumper, good proportional brake controller, wdh w/ integrated sway control, some basic dishes, silverware, cups, pots/pans, toiletries, cleaning supplies, trash can, heavy duty wheel chocks, lynx levelers, wooden blocks to put under tongue and stab jacks, flashlights, lantern, chairs to sit on. you can get the patio mat and awning lights down the road. remember you don't need every gadget and cool thing right away. pace yourself as this is an expensive hobby. Also videotape your pdi. make them show you how to winterized and dewinterize, hitch up and unhitch your wdh on that video. Do yourself a favor and read about the
geo method for black tanks. Congrats on the new TT and may it bring you many happy camping trips.
